I didn't see much in the way of eval changes in 18.9... it is mainly a more
aggressive "book learner" with a few other minor changes.  The evals should be
pretty similar (not identical however).

18.10 is more different, as bishop scoring has changed after several hours of
GM discussion.  Castling is handled a bit differently too.
